A startlingly-thin Demi shows up to the same shindig as Ashton — find out all the details!

Ashton, 33, and Demi, 49, both attended a CAA Golden Globes party on Jan. 13 at Soho House in Hollywood, and though they managed to avoid each other for most of the night, the pair did catch up, the New York Post reports.

“Within five minutes of them seeing each other, Ashton did come over,” a source says. “It was a crowded room so he made his way over. Demi and Ashton, and Madonna and Sean [Penn], were talking and hanging out. Ashton and Demi didn’t arrive together, or spend the whole night together, but it was 100 percent normal. There wasn’t an issue.”

The next day, Demi was spotted at the Cinema For Peace event at the Montage Hotel in Beverly Hills with her daughter Rumer Willis, and she looked PAINFULLY thin. This split is taking a huge toll on her health — we feel so bad!
